- ΔNi,j If positive, ΔNi,j denotes the number of bits that have to be repeated in an encoded block on TrCH i with transport combination j in order to produce a radio frame.
- If negative, ΔNi,j denotes the number of bits that have to be punctured in an encoded block on TrCH i with transport combination j in order to produce a radio frame.
- If null, no bits have to be punctured or repeated (i.e.: the rate matching is transparent and the content of the radio frame is identical to the content of the encoded block on TrCH i with transport format combination j.
